To all whom it may concern,.-

Bc it known that we, CHARLES H. HARD, ORRIN G. FRANKs, and ALBERT E. LooMrs, of Oneida, in the county of Madison, in the State of New York, have invented new and useful Improvements in Machines for W'eaving Wire Mattresses, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates. to the weaving of wire mattresses composed of longitudinallyintertwined spirally-coiled wires; and the invention consists in a novel organization of a machine which is capable of weaving mattresses with great rapidity and accuracy, and at a minimum expense of manual labor and minimum loss of material, all as hereinafter fully described, and set forth in the claims.

In the annexed drawings, Figures 1 and 2 are elevations of opposite sides of the main portion of the machine. Fig. 3 is atop plan View of the same. Fig. 4 is a vertical transverse section on line a; so, Fig. 1. Fig. 5 is a horizontal transverse section on line WV W, Fig. 4. Fig. 6 is an enlarged vertical transverse section of the fabric-supporting rollers, taken on line y y, Fig. 1. Fig. 7 is an enlarged end view of the aforesaid rollers, showing the means for transmit-ting intermittent rotary motion to the same. Fig. 8 is an enlarged transverse section on line ,e e', Fig. 1. Fig. 9 is a detached side view of the wheel, which is provided with means for converting the continuous rotary motion into an intermittent motion. Fig. 10 is an edge view of the same.

Fig. 13 is a transverse section on line O O, Fig. 12. Fig. 14. is an enlarged detached side view of the devices employed for impart-ing oscillatory motion to the lever or arm which transmits reciprocating motion to the frame which carries the fabric-supporters, and Fig. 15 is an end view of a modilication of the fabric-supporters.

Similar letters of reference indicate corresponding parts.

A rcpresent-s the main supporting-frame,

which is preferably composed of cast-iron. This frame is formed with a horizontal prolongation and with longitudinal guides, in which is seated movably a supplemental frame A', extending lengthwise of the aforesaid prolongation of the frame A and provided with a longitudinal slot A, extending vertically through it. Upon this supplemental frame, at opposite sides of the aforesaid slot thereof, we mount our devices for supporting the fabric or woven portionof the fabric during the process of weaving. These fabric supporters or holders may be of any suitable form adapted to grasp the fabric between the two last woven strands of wire and hold the fabric suspended therefrom, said fabric passing through the slot A. Two forms of fabricsupporters are illustrated in the annexed drawings, the preferred form consisting of prolonged rollers B, disposed at opposite sides of the slot A and extending from end to end of the supplemental frame A', and provided with longitudinal grooves in their exterior, as shown in Figs. 6 and S'of the drawings. A modification of said rollers is illustrated in Fig. 15 of the drawings, each of said rollers consisting of a series of small rollers BB B', arranged in juxtaposition to each other and pivoted to annular' spiders secured to the ends of a shaft extending lengthwise of the supplemental frame A. In either case said fabric-supporting rollers B or B are journaled to suitable bearings on t-he frame Af and are made to turn in unison and with their top portions towa-rd each other by means of intermeshing pinions a a, secured to the rollers at one end thereof. To the opposite end of one of the said rollers is attacheda ratchet-wheel b, with which engages a pawl c, pivoted to an arm c', which is hung on the journal of said roller, as shown in Fig. 7 of the drawings, and receives an oscillatory motion by the mechanism hereinafter described.

C represents the main driving-pulley mounted ou a shaft C', which is extended horizontally across the frame A and journaled in suitable boxes. To this shaft is also firmly attached a pinion D, which meshes with a gear-Wheel E, secured to a horizontal shaft E', mounted on the frame A. To the shaft E' is also rigidly attached a cam d, which, during the rotation of the shaft, is caused to encounter one end of a lever e, which is pivoted to the frameA and connected at the opposite end to the arm c by a pitman e'. Said arm thus receives an intermittent oscillatory motion, which by means of the pawl c imparts an intermittentrotary motion to the ratchet-Wheel b and to the rollers B B. Between the said ratchet-wheel and ends of the rollers B B is a bracket F, secured vertically to the top of the frame A, and on said bracket slides vertically the knife f, which has opposed beneath it a stationary knife f', as best seen in Fig. 6 of the drawings. The latter knife has its cutting-edge immediately below the line of the longitudinal passage between the rollers B B, and the other knife stands normally raised sufficiently from the lower knife to allow the coiled wire to pass between them and into the aforesaid passage between the rollers. The upper knife receives reciprocating motion by means of a lever g, pivoted to the bracket F and having a tongue g', sliding in a groove in block g", pivoted to the knife, as shown in Figs. 6 and ll of the drawings, and said lever receives intermittent oscillatory motion by means of a cam d', fixed to the shaft E', and a lever e, pivoted to the'frame A, and having one end in the path of the cam d and the opposite end connected to the lever g by a pitman 6"'.

The sliding frame A receives an intermittent reciprocating movement by means of an arrnnwhich extends radially from the shaft E' and has a cam h' projecting from its side.

.An arm 't' is pivoted or suspended oscillatory from the top of the frame A, and has its free end in the path of the cam h. To said end of the arm rl is pivoted a latch i', which has its lower end bent to one side, and at opposite sides of the upper end of said latch are stops j 7' on the arm t', as shown in Fig. 14: of the drawings. On the frame A is fulcrumed a lever k, one end of which is connected to the arm t' by a rod lo', and the opposite end of said lever is connected to the sliding frame A", as shown in Fig. 1 of the drawings. During the rotation of the shaft E' the cam h first comes in contact with one side of the upper end of the latch t", which rests in an inclined position against one of the stops j, and in passing down over the length of said inclined latch and pressing upon the same the cam h' crowds the arm z'- to one side, and in passing over the bent lower end of the latch beneath the fulcrum thereof, said latch is turned on its pivot so as to throw the upper end thereof over against the other stop j, and is thus inclined in an opposite directlon, as illustrated in Fig. 14 of the drawings. In the next revolution of the shaft E' the cam h' strikes the opposite side of the l'atch t', and in passing down over the same the said cam draws the arm z' back toward the shaft E' and into such an angle of inclination as to carry the latch nearer to a vertical position, and thus only a slight pressure of the cam is required on the lower extremity of the latch to cause the same to be tilted in the opposite direction. By this means the arm 'L' receives an intermittent oscillatory motion, which imparts an intermittent reciprocating motion to the frame A'.

H I-I represent the reels, on which are wound the wires from which the mattress is to be manufactured.

G G are feed-rolls,between which the wire passes from the reels. Said rolls are arranged horizontally in a frame G', which rises from the top of the frame A. To the side of the frame G', facing the reels II H, is secured a guide Z, which conducts the' wires from the reels to the feed-rolls. To the opposite side ofthe frame G is secured the wire-coiler I, which imparts a spiral shape to the wire. Said coiler is in range with the space between the rolls B B, and is of the usual form, consisting of a spirally-grooved mandrel- I', secured stationary in a sleeve I", as shown in Figs. 1l and l2 of the drawings. Between the end of said coiler and the knives ff', and in line with said coiler and space between the rollers B B, is a threader L, which passes the coiled wire into the previously-woven wire, said threader consisting of a spindle n, which is provided with a spiral wire-guiding groove n'. in its exterior, and is seated in a surrounding sleeve m, as shown in Fig. 1l of the drawings.

In order to depress the threader with the knife f, said parts are connected together by a screw o, passing through a Vertical slot in the bracket F and secured to a verticallymovable arm L', which carries the threader, as shown in Fig. l1 of the drawings. The feed-rolls are provided at one end with gears J J of equal diameters and meshing with each other, and receive motion from the wheel E by an intermediate pinion N, which is preferably pivoted to an arm N', hung on the shaft of one of the rolls G, as shown in Fig. l of the drawings. By raising the arm N' the pinion N can be released from the wheel E when desired to stop the feed-rolls.

In order to cause the feedjrolls to stop automatically when the wire in process of weaving has reached the end of the mattress to be woven, we form the toothed face of the wheel E of a width to afford a separate engagingface for each of the driving-pinion D and the pinion N, and form that portion which engages the latter pinion with a blank segmental portion O, as best seen in Figs. 9 and lO of the drawings, and concentric with the wheel E, preferably to the shaft E', we pivot an arm P, which extends to the periphery of the Wheel E, and is formed thereat with a toothed section O', corresponding to the cogs of the Wheel E and occupying a portion of the blank space O. This end of the arm is held normally in the advance end of the blank space by means of a suitable spring P', con- IOO IIO

' spindles of the reels H H.

nected to the arm and wheel. A latch K is attached to the wheel and adapted to engage and hold the free end of the arm P in the advance end of the space O, and a cam K is attachedl to the frame A in such relative position as to cause said cam to throw the latch out of engagement with the arm P when the latter engages the pinion N. The arm being liberated, as aforesaid, ceases to rotate with the wheel E, and therefore fails to impart motion to the pinion N. In order to allow the said automatic stop-motion to be regulated in accordance with the length of the mattress to be woven, we employ one or more cogged sections 5, which are detachably secured to the end of the blank space O in the wheel E, and thus vary the length of the free movement of the arm P.

The reels H I-I receive rotary motion from a gear-wheel Q, attached to the shaft of one of the feed-rolls G, which gear-wheel transmits motion to a gear-wheel Q on a horizontal shaft p underneath the reels by means of a train of gears 1 2 3 4, as best seen in Figs. 2 and 3 of the drawings. The shaft p is disposed diametrically across the axis of the reels and journaled in suitable bearings on the, frame A, and has mounted on it two frictionwheels R R, which slide on splines on the shaft. Said friction-wheels bear with their peripheries on friction-faces on the under sides of wheels S S, secured to the vertical Parallel with the shaft p are .two screws T T, journaled to the frame A, and on said screws are nuts T T provided with laterally-projecting arms q q, which engage with circumferential grooves in the hubs of the wheels R R, as shown in Fig. 5 of the drawings. By turning said screws the wheels R R can be moved toward or from the axis of the wheels S S, and thus the motion of the latter is increased or diminished accordingly. The ends of these screws are provided with cranks q q', by which to turn them.

To allow the mot-ion of the entire machine to be stopped when desired, we mount the driving-pulley C loosely on the shaft, so as to allow it to turn freely and slide longitudinally thereon, and to the shaft C we rigidly secure a clutch U, adapted to engage and retain the pulley by sliding the latter toward and from the clutch. A two-armed lever r, pivoted to the frame A, has one arm engaged with a circumferential groove in the hub of the pulley, and the other arm of said lever is connected with one end of a lever r by a rod fr. Said lever r' is pivoted to the frame A and has its opposite end connected to a hand-lever s, by which to operate the said levers r and r so as to throw the driving-pulley C in and out of engagement with the clutch U.

In order to cause the machine to stop automatically in case the wire in process of weaving accidentally runs out of its requisite course of intertwining with the previouslywoven wire, we employ an electric stop-motion consisting of electrodest t of the form of;

metallic rods supported insulated on t-he frame A and extending the entire length of the space between the rollers B B, over which space they are arranged parallel therewith and in proximity thereto, as best shown in Figs. 3 and S of the drawings. Said electrodes and the metallic frame A are in the electric circuit, of which V denotes the battery. The hand-lever s is connected to an arm u, pivoted to the frame A, and to said arm is also connected a pendent rod u', which receives a downward draft by a spring u, and is formed wit-h a rack c. With this rack engages a toothed quadrante on the end of a horizontal latch o, fulcrumed on a suitable support on the frame A. Facing the opposite end of said latch is an armature provided with a catch w, adapted to engage and release the latch, and drawn toward the same by a spring w.

x denote electro-magnets in circuit with the battery V and in position to draw the armature with the catch w away from the latch c.

In setting the machine in motion the handlever is swung into such a position as to cause the before-described levers to force the driving-pulley Cinto engagement with the clutch U, and when this is effected the rod u swings the latch fu into a position to allow the catch w to engage and retain the same, as illustrated in Fig. 1 of the drawings. In case the wire in process of weaving leaves its requisite intertwining course it comes in contact with the electrode t, and thereby closes the electric circuit. The magnets being thus energized draw the armature with the catch 'w away from the latch 'v' ,which, being released, allows the spring u to draw down the rod u, and thereby causes the levers to throw the driving-pulley C out of engagement with the clutch U, and consequently the machine is stopped.

The described mechanisms of the machine are so arranged in relation to each other that in the process of weaving the mattress the feed-rolls G G draw the wires from the reel under the proper tension, which wires are passed through the coiler I, which imparts a spiral form to them. The wires thence pass to the threader L, which guides and pushes them into and along the space or channel between the rolls B B above the axis thereof, and at the same time impartsa rotary motion to the wires. The rolls B B remain stationary in the meantime. When the wires have thus been carried along between the rolls B B to a distance equal to the length of the mattress to be woven, the feed-rolls G G automatically stop, and during this time of rest the pawl c turns the rolls B B sufficiently to carry the aforesaid wires slightly below their previous position without losing hold thereof, and then the knife f descends and severs the wires. At the same time the sliding frame A is moved slightly longitudinally, and thereby the upper helices of said wires are carried IOO IIO

out of range with the wire held in the threader L. By the time this is effected the feed-rolls G G are again set in motion, and the coiled wires which are then passed along between the rolls B B intertwine with the upper helices of the wires held between the-rolls, as before stated. In this manner each pair of successive wires intertwines with the last preceding wires, and each turn of the rolls B B allows a corresponding portion of the woven fabric to drop. The fabric thus woven is supported Vin a suspended position from the rolls and passes down through the slot A" in the frame A.
